Any info on this airline/services would be appreciated. A good friend of mine in traveling on them to Luxembourg in mid-August and would love to hear. Luxembourg is a great small city, I took the train there from Brussels last month for a quick day trip and found it charming as well as as picturesque, not to mention completely walkable. If going by train don't be dismayed by the dreary area of foreign banks & fast food restaurants around the Central Station, just head left or straight ahead to the "old town".
